Soil Quality: A Review Of The Science And Experiences In The Usa, B. J. Wienhold, S. S. Andrews, D. L. Karlen
Soil Quality: A Review Of The Science And Experiences In The Usa, B. J. Wienhold, S. S. Andrews, D. L. Karlen
Douglas L Karlen
An increasing human population is placing greater demand on soil resources, and as a result degradation is taking place in many regions of the world. This is critical because soils perform a number of essential processes including supporting food and fiber production, influencing air quality through interaction with the atmosphere, and serving as a medium for storage and purification of water. The soil quality concept was introduced to complement soil science research by making our understanding of soils more complete and helping guide the use and allocation of labor, energy, fiscal, and other inputs as agriculture intensifies and expands to …

Soil quality is a concept that is useful as an educational and assessment tool. A number of assessment tools have been developed including: the Soil Conditioning Index (SCI), the Soil Management Assessment Framework (SMAF), the AgroEcosystem Performance Assessment Tool (AEPAT), and the new Cornell “Soil Health Assessment”. The SMAF and AEPAT were developed as malleable tools for assessing soil response to management. The Cornell Assessment builds on the SMAF approach to score laboratory tests in terms of soil function. This paper updates efforts to improve availability and utility, implementation, and future research goals associated with the SMAF. Additional scoring curves …

Various soil management or quality assessment tools have been proposed to evaluate the effects of land management practices on soil, air, and water resources. Two of them are the Soil Management Assessment Framework and the Soil Conditioning Index (SCI). This study was conducted to test the hypothesis that the Soil Quality Index (SQI) estimated by the Soil Management Assessment Framework can detect more minute changes in soil management than SCI and to test SCI response to other soil quality (SQ) indicators. These SQ indexes were tested on irrigated cropping systems near Fort Collins, Colorado, that included no-till and conventionally-tilled corn …
Corn Residue Harvesting Effects On Yield Response To N Fertilization, Jose L. Pantoja, John E. Sawyer, Daniel W. Barker, Mahdi Al-Kaisi
Corn Residue Harvesting Effects On Yield Response To N Fertilization, Jose L. Pantoja, John E. Sawyer, Daniel W. Barker, Mahdi Al-Kaisi

Producers have many choices of diverse tillage practices for their corn (Zea mays L.) production systems. However, no-till has become an important soil management practice to help reduce water and wind erosion, as well as nutrient runoff, while conserving soil moisture for crop use. No-till systems also help farmers by saving labor and time, as well as reducing farm costs due to less equipment and fuel consumption. Nevertheless, no-till production is typically more successful and has higher crop yield on moderately to well drained medium-textured soils (Bitzer, 1998), compared to soils with poor internal drainage and high clay.

Landscape Management For Sustainable Supplies Of Bioenergy Feedstock And Enhanced Soil Quality, Douglas L. Karlen, David J. Muth Jr.
Landscape Management For Sustainable Supplies Of Bioenergy Feedstock And Enhanced Soil Quality, Douglas L. Karlen, David J. Muth Jr.
David J. Muth
Agriculture can simultaneously address global food, feed, fi ber, and energy challenges provided our soil, water, and air resources are not compromised in doing so. As we embark on the 19th Triennial Conference of the International Soil and Tillage Research Organization (ISTRO), I am pleased to proclaim that our members are well poised to lead these endeavors because of our comprehensive understanding of soil, water, agricultural and bio-systems engineering processes. The concept of landscape management, as an approach for integrating multiple bioenergy feedstock sources, including biomass residuals, into current crop production systems, is used as the focal point to show …
